A 16-year-old boy's toe had to be amputated after a motorist lost control on a bend and pinned him against a wall, a court heard.

Witnesses ran to help the teenager at the scene of the crash in Bolton Road, Atherton, on November 22, 2010, after he was struck by a Vauxhall Vectra, being driven by Nizamuddin Patel, aged 36, of Saltwood Grove, Bolton.

The victim’s leg was so badly broken that a bone was protruding and one of his big toes had to be amputated following the crash.

Henry Riding, prosecuting, told Liverpool Crown Court that witness Stephen Gaskell was driving along Derby Street, Bolton, when the Vectra overtook him at about 40mph in the 30mph area, which took him by surprise as it “came out of nowhere”.

Further on, he saw it overtake another vehicle, but when they reached the junction of St Helens Road and Hulton Lane it had been halted by traffic lights.

When they changed to red he saw it right behind another car and it overtook it and pulled away.

Mr Riding claimed the driver again caught up with Patel when he was stopped at the next set of lights, and when they changed Patel accelerated away.

Mr Gaskell saw two cars coming from the opposite direction and one moved into the nearside lane “taking evasive action”.

Mr Riding said Patel had pulled back into the correct lane and drove on. Mr Gaskell then saw the Vectra had slewed sideways and had been hit by a Vauxhall Astra coming from the opposite direction.

But before it had been struck by the other car, the Vectra had careered on to the nearside pavement and collided with the teenage pedestrian, said Mr Riding.

Patel was arrested at the scene and told police he had been blinded by the lights of the vehicle behind him. He denies dangerous driving.

The case continues.
